14 Claims. 1

This invention relates generally to, machines used in perforating cardsfor use in statistical machines, and more particularly to anelectromechanically operated punch mechanism adapted to perforate a cardin accordance with a predetermined code, the invention being morespecifically applied to portable machines which perforate a carriagepropelled card in a column by column manner.

As is now well known to the art, one type of statistical card in commonuse is the Powers card which is produced in twowidely used forms,namely, the forty-five column card. and the ninety column card. In theforty-five column card each column contains twelve index positions,thereby permitting each of the ten digits to be indicated by a singleperforation, and the alphabet letters by a combination of one or moreperforations in a column. The ninety column Powers card is dividedhorizontally into two zones, an upper and lower zone, each zonecontaining forty-five columns of six index positions each, therebyrequiring each of the ten digits and the alphabet letters to beindicated in each card column by one or more perforations therein, inaccordance with a pre-determined code. In the code commonly known as theninety column code and used with this type of Powers card, the and allodd digits are consecutively represented by a perforation in singlesuccessive index positions from the top of a, column, and all evendigits are represented by a multiple perforation comprising perforationsin the next lower odd digit -index position in combination with the ninedigit index position. This latter type of card, together with the codeadapted for use therewith, is disclosed and more fully described inpatent to W. W. Lasker 1,780,621, issued November 4, 1930. It is to amachine for punching such type of card that the present inventionrelates, and in the embodiment herein disclosed the code for indicatingnumerical data in six position card columns as therein described isherein adopted.

Heretofore, it has been the practice to provide all card perforatingmachines of the type described with a traveling card carriage andassociated escapement mechanism capable of positioning the card in anumber of separate positions equal to the number of columns across theentire width of the card. Accordingly, such machines for use with Powerstype cards were pro- 'vided with carriages and carriage escapement racksof forty-five column capacity. This practice has been continued inadapting such ma-i chines for use with plural zoned cards, with theresult that in all machines so adapted a return of the card carriage hasbeen required between punching of the separate zones of the card, andfor this reason necessitating more than'one cycle of carriage operationfor a complete punching of one plural zoned or ninety column card. Thispractice necessarily likewise required provision of means forselectively activating one of two groups of punches in a plurality ofpunch combinations for each digit in every carriage position, dependingupon the card zone in which a perforation was desired.

The present invention may be embodied in a machine provided with theusual base with a card carriage and keyboard mounted thereon. However,instead of the usual single row of twelve reciprocable punches, thepresent machine is provided with two separate and independently drivenrows of punches, or, accordingly a separate row operable in eachseparate zone of the card. The two rows of punches are set in separatepunch supporting blocks extending over the path of the card carriage,near opposite ends of the key actuated mechanism, and both rows aresimultaneously conditioned upon depression of the same digit key. Thelinear distance between said separate punch supporting blocks is suchthat, as a. card is drawn by the card carriage from right to left belowboth rows of punches, the first column of the lower zone is in positionfor perforation by punches in one of said rows of punches uponcompletion of the punching of the last column of the upper zone by theother of said rows of punches. Spacing mechanism is provided foradvancing the card column by column through the respective punchingchambers, with means responsive to the relative position of the card inthe machine for disabling that row of punches operable on that zone ofthe card in which a perforation of the card in such position is notdesired. A key actuated carriage release mechanism is provided fordisabling the carriage escapement mechanism so as to permit return ofthe carriage to its extreme left hand position wherein the card may beeither inserted or withdrawn from the machine.

The present machine is provided with a card carriage capable of beingpositioned by the escapement mechanism in a number of positions equal tothe total number of columns in a, plural zoned card, in the presentdisclosure the carriage mechanism being of a ninety column capacity.Accordingly, such carriage mechanism, in cooperation With the uniquearrangement of the plural rows of punches, permits a complete punchingof all columns of a. plural zoned card within one continuous anduninterrupted series of punching operations, and the additionaloperation, previously required, of returning the carriage to normalstarting position upon completion of punching in one zone, is therebyeliminated. The entire card may be punched within one operational cycleof the card carriage, upon completion of which the card is in positionfor removal from the machine. It follows that such a feature avoids thenecessity of providing a machine of this type with means for selectivelyactivating one of a plurality of punch combinations in each cardcarriage position, and the pos-' sibility of inadvertent operationalerror in failure to so select correctly resulting in the perforation ofthe wrong card zone is thereby eliminated.

It is, therefore, the principal object of this invention to improve theconstruction and design of card punches to permit the perforating of allcolumns of a plural zone statistical card within one cycle of itscarriage operation.

It is a further object of this invention to simplify the art of cardpunch operation by eliminating the carriage return upon the completionof punching in one zone of a plural zone data card.

It is a further object of this invention to avoid, in card punchoperation, the possibility of operational error of causing the machineto perforate in the unintended zone of a plural zone data card.

A clearer concept of the invention, with additional objects and featurestherein apparent, may be derived from the following description of thedrawings, in which Fig. 1 is a view of the machine in isometricperspective;

The machine embodying the present invention is similar in constructionand operation to that disclosed in the patent to E. 0. Roggenstein,

2,151,232, issued March 21, 1939. The mechanism is mounted on a base l5,which is over double the length of the usual statistical punch card. Thebase is formed with a shallow recess l6 which extends the full length.of the base, and is the same width as a statistical card I1, thusforming a guide therefor. The base i5 is further provided with a o e l8tending its entire length in which is mounted a carriage rail 19 onwhich is mounted for longitudinal travel a carriage escapement rack 2|.The carriage esoapement rack 2| is provided near each end thereof with'double flange rollers 22, as best seen in Fig, 10, which rollers rideon said carriage rail, and are held against vertical displacementtherefrom by the overhanging arm of a guide bar 23 amxed to base l5.Secured to the left end of carriage escapement rack 2| is an arm 24projecting at right angles thereto carrying a concavely curved fingerpiece 25 and a horizontally projecting tongue 26, the bottom surface ofwhich tongue rides on the floor of recess 16 in base IS. The forwardfree end of said tongue is notched to engage therein the edge of a cardl1 and thus prevent longitudinal or vertical displacement of the card inrelation thereto. A similar arm 21 (Fig. 4) is secured to the right handend of the carriage escapement rack 2| and acts as a card stop bysimilarly engaging the opposite edge of the card, the two arms therebycomprising a carriage for holding the card in fixed relation to thecarriage esoapement rack while being drawn thereby beneath the punchingmechanism. The card is inserted in the machine when the carriage is inits extreme left hand position, at which time the card carriage ismanually urged to its extreme right hand position preparatory topunching. The carriage esoapement rack is then urged to the left, stepby step, by a pinion 28 (Fig. 6) driven by a spring 29 and engaging withthe rack 2|, upon release of key controlled esoapement mechanism ashereinafter described.

The card carriage may be spaced, either in conjunction with theoperation of any digit key, as will be hereinafter described, or bydepression of the space key 30, the stem 3| of which, as shown in Fig.3, is pivoted to one arm of a bell-crank 32 pivotally mounted at 33 to abracket 34 secured to base |5. The other arm of bell-crank 32 ispivotally connected at 35 to one end of a link 36 pivoted at itsopposite end at 39 to a lever 40 secured to a rock shaft 4|. Rock shaft4| is suitably journaled in arms 38 formed on a punch supporting blockhereinafter described, and has also secured thereto a pair of rock arms42 one of which extends below its pivot point and carries a lug 43projecting beneath an esoapement bail 44 which is pivoted through itsbent ends to brackets 45 affixed to base i5. A pin 46 on the esoapementbail 44 extends through holes cut in an esoapement pawl 48 and an arm ofa bellcrank 41 jointly pivoted to a bracket mounted on base i5. Alsopivoted on bracket 50 is a holding pawl 5|. The esoapement pawl isnormally pulled into engagement with a tooth of the carriage esoapementrack 2| by spring 52. The manual depression of thespaoe key 3|) resultsin the counter-clockwise rocking of bell crank 32 moving link 36 to theleft against tension of spring 31 to rock shaft 4|, thereby rockingescapement bail 44 through lug 43 on the extended rock arm 42. Therocking of ball 44 raises pin 45 which disengages the esoapement pawlfrom the rack, and at the same time rocks the bell-crank 41, the otherarm of which is bent and provided with a pin 49 engaging a slot in theholding pawl 5|. The rocking of bell-crank 41 rocks the holding pawl 5|simultaneously into engagement with another tooth of the carriageesoapement rack. The pivotal connection of esoapement pawl 48 withbracket 50 is of the pin and slot type, so that this pawl, upondisengagement with the carriage escapement rack, is urged by spring 52to the right a slight distance as limited by said slot, which distanceis sufhcient to prevent the return of the pawl 48 to engagement with thesame tooth of the rack, Release of the space key allows spring 52 topull the escapement pawl 48 back into engagement with the nextsucceeding tooth of the carriage escapement rack, at the same timerocking the holding pawl 5I out of engagement with the rack through theaction of pin 46, bellcrank 81, and pin 89. The carriage is thusrestrained by the escapement pawl from moving to the left a distancegreater than that between two adjacent teeth, which distance is equal tothe columnar spacing of a punch card, and in this manner a single columncarriage spacing is efiected.

The card carriage may be released for return to its extreme left handposition by manual depression of the release key 53, the stem 58 ofwhich is pivoted, as shown in Fig. 2, to one arm of bell-crank 58mounted on a bracket 55 secured to the base I5, The other arm ofbellcrank 58 is connected to one end of a link 59, the other end ofwhich is pivoted to an arm of a bell-crank 60 mounted .on a bracket 56,likewise secured to base I5. The free arm of bellcrank 60 projectsbeneath a lug 6| on escapement pawl 08. Depression of the release keyrocks bellcranks 58 and 60 clockwise, causing the free arm of saidbell-crank 50 to engage the lug 6|, thereby rocking the escapement pawlcounter-clockwise to disengage it from the teeth of the carriageescapement rack. The lost motion between the hole in escapement pawl 88and the escapement bail pin 46 permits the pawl to be rocked out ofengagement without the concurrent rocking of bell-crank 81. Due to thebell-crank 41 not being rocked, holding pawl 5| remains inefi'eetive.IAC- cordingly, in this operation both the escapement pawl and holdingpawl are simultaneously free from the escapement rack, permittingrelease of the carriage to its extreme left hand position.

The ten digit keys 63, Release key 53, and Space key 30 are arranged inthree rows as shown in Figs. 1, 6, and 7. Each digit key comprises thebutton 53 mounted on a rectangular stem 62 extending through rectangularperforations in each of two guide plates 64, securely mounted on twoframe plates 55, 66, and which are in turn secured to base I5 to form asupporting structure suitably enclosed by a cover plate 61. The key stemfor each of the center row of keys extends vertically downward throughsaid guide plates to rest on a stud 69 on one arm of a bell-crank 58,while the key stem of each of the outer row keys is cut off below thelower guide plate and carries, instead, an inwardly projecting arm I0,bent downward through a perforation in lower guide plate 68 to similarlyrest on a stud on the supporting arm of its corresponding bell-crank 68.Said bell-cranks are loosely mounted on a fixed cross shaft II suitablysupported by the two frame plates 65 and 66, and are normally urgedcounter-clockwise by action of a spring I2, Each of said bell-cranks 68is formed with a horizontal arm projecting to the right directly above arow of steel balls I3 in a slotted housing extending between the saidtwo side frame plates in such a manner as to constitute a ball lockmechanism,

the operation of which is well known to the art, the purpose of which isto allow no more than one bell-crank 68 and corresponding actuatingdigit key to be depressed at one time. The vertical arm of eachbell-crank 68 has pivoted thereto at I5 a link I6 having a slot 11 toengage a pin I8 on a lever "I9 which is secured by a collar to a rockshaft suitably journaled in the two side frame plates 65 and 66.Likewise secured by a collar to each rock shaft 80 are two or morefingers 83 extending downwardly to engage studs 82 on individual punchconditioning slides 8|. Said punch conditioning slides, as seen in Figs.4 and '7, are guided through comb plates 88 and 85 secured to punchsupportingblocks 86 and 81, respectively, to rest loosely near each endthereof, on the heads of punches 88 and 89, and are normally urged tothe right, as shown in Fig. 7, by action of springs 90. Motion impartedby depression of a digit key 63 is carried through bell-crank 68, linkI6, lever I9, rock shaft 80, fingers 83, to shift the punch conditioningslides engaged thereby to the left wherein shoulders 9| and 92 at eachend thereof will act as punch gags for the punches 88 and 89,respectively, as hereinafter described. The punches 88 (Fig. 7), forperforating the lower zone of a Powers ninety column punch card, aresupported as aforementioned in the block 88 and a guide block 93, bothof which are secured to base I5 and extend over the card bed at the lefthand end of the key actuated mechanism. The punches 88 are aligned in arow of twelve to correspond with the twelve index positions from top tobottomin a Powers type statistical card, and, likewise, to support oneend of the twelve punch conditioning slides 8|. However, only the frontsix of said punches 88 ar effective for perforating a card, they beingpositioned over the six index positions comprising a column in the lowerzone of a card. The rearmost six punches 88, positioned over the sixindex positions of the card's upper zone, are dummy punches with thecutting edge eliminated, their purpose being to support the six rearmostpunch conditioning slides BI, and their incidental depression duringactuation of the punches 88 is ineffective to cause a card perforation.All of said punches 88 are normally urged -upward by compression springs94 resting on guide block 93 and pressing against the punch headsthereby allowing free passage of a punched card therebelow. Punch dies95 are secured in the base I5 in any well known manner, A hammer bail 96is pivoted to shoulders on the block 88 and is rocked by a hammer bailarm 97 pivotally connected thereto and extending downward through anopening in base I5, where it is pivoted to a bell-crank I02 mounted onthe under side of the base. Said bell-crank is connected by link I00 toan armature IOI cooperating with electromagnet I03, both armature andmagnet being suitably secured to the underside of the base. Theenergization of the magnet rocks its armature I III counter-clockwise(Fig. 6) against the tension of spring I08 to rock hammer bail 96clockwise through link I00, bell-crank I02 and hammer bail arm 91,thereby depressing whichever shoulders SI of slides 8| have beenlaterally shifted into its path, and in so doing driving the associatedpunch or punches through the card II. Deenergization of magnet I08permits return of the parts to normal or inactive position by springI08. The construction and operation of the upper zone punch mechanism issimilar to that of the lower zone just described, except that the sixefiective punches are the rearmost six in the row of punches I09, beingaligned with the six column positions in the upper zone of a card, whilethe front most six are the dummy or inefi'ective punches in said row.Accordingly,

a description thereof need be only briefly noted here whereinenergization of magnet I03 rocks armature I08 against the tension ofspring III, and rocks hammer bail I01 through link I09, bell-crank IIand hammer bail arm I to depress whichever shoulders 32 of punchconditioning slides 8| have been laterally shifted into its path,thereby driving the corresponding punches 89 yieldably supported bysprings H2 in block 81 and guide block II3 through the upper zone of thecard I! and into punch dies I I4.

The card carriage is automatically spaced, upon the actuation of anypunch, by means of spacing bails H6 or II! which underlie the punchconditioning slides of each end thereof. Spacing bail IIB (Figs. 3, 7,and 8) is carried by arms 42 integral therewith secured to the rockshaft M as heretofore described, and, spacing bail I I1 is carried by apair of arms I I8 secured to a rock shaft H9 journaled to arms I20formed on the punch supporting block 81. The rearmost arm III! of bailII'I extends downward and carries a lug I2I (Fig. 3) projecting directlybeneath the escapement bail 44. Thus the depression of a punchconditioning slide 8I (Fig. 3) by hammer bail I01 rocks spacing bail IIIclockwise to raise escapement bail 44 through lug I2I and, similarly,the depression of a punch conditioning slide by hammer ball 96 rocksspacing bail IIIi counter-clockwise, likewise raising escapernent bail44 through the lug 43. Theefiect of raising the escapement ball 44causes carriage spacing, as has been previously described in connectionwith the operation of the space key. In this manner the depression ofany punch slide by either hammer bail simultaneously actuates one or theother spacingbaiis, resulting in the spacing of the carriage to positionthe card I! in preparation for perforating the next succeeding column.

The use of rock shafts 80 (Figs. 5 and 8) in a machine of this typeprovides a simple and expedient means for conditioning a. plurality ofpunches as is required in code punching, by the depression of only onedigit key. As hereinbefore mentioned, the punch code used in the presentdisclosure is one in which the zero and all odd digits are consecutivelyrepresented by a perforation in a single index position, and the evendigits are represented by perforations in the next lower odd digit indexposition in combination with the "nine digit index position. Ac--cordingly, those rock shafts 80 linked to the zero and odd digit keyseach carry two fingers 83 for shifting one punch conditioning slide 8Iefiective on punches operable in each of the two card zones, while thoserock shafts linked to the even digit keys each carry four fingers 83 forshifting two punch conditioning slides in accordance with the code toeffective position over punches operable in each of the two card zones.Fig. 9 is a fragmentary view showing mechanism actuated by the six digitkey wherein it can be seen that the rock shaft 80 carries four fingers83 for shift. ing four punch conditioning slides 8|, two for the upperzone and two for the lower. Number "six" being an even digit andrepresented in the six position code by perforations in the fourth andsixth positions from the top of a column, the slides shifted bydepression on the "six digit key are, accordingly, those conditioningtwo of the punches 89 aligned with the fourth and sixth position in thepunch cards upper zone, and those conditioning two of the punches 8Ilaligned with the fourth and sixth columnar position of the card's lowerzone. Thus it is apparent that upon depression of a digit key, theresultant perforation can be effected in either the upper or lower zoneof a ninety column card. depending on which of the two hammer balls 96or I 0'! is caused to rock in cooperation therewith. As can be seen byreference to Figs. 4 and 5, it is obvious that any code combination canbe obtained by grouping the fingers 83 on the cross shafts 80 in such amanner that the rocking of any shaft 80 by an individual key will resultin the positioning of one or more punch slides 13! in accordance withthe desired code.

An electrical circuit to either magnet I03 or I08 is closed upondepression of any digit key through the medium of a contact bail I25(Figs. 4 and 6) extending beneath the horizontal arms of key operatedbell-cranks 68 which bail is carried by arms I24 and I26 mounted on studshaftsin side assembly frame plates 65 and 66. Ball arm I20 extendsbeyond the pivot point and has pivoted on its free end a. contact pawlI2'I (Figs. 6 and 12) pulled by spring I3I in a counter-clockwisedirection against a stud B2. A lip on the contact pawl I2I normallyengages the lower spring contact I29 of a pair of contacts I29 and I28suitably insulated and secured to side frame plate 66. A link I34,formed as shown and pivoted to the contact pawl I21 has a slot near itslower end through which passes a tie link I35 pivoted to hammer bailarms 91 and I05. Depression of a digit key rocks the contact bail I25clockwise, raising contact pawl I21. closing contacts I29, I28 tocomplete an electrical circuit (Fig. 11) through a transfer switchhereinafter described, to either magnet I03 or I06. Upon energization ofeither magnet its associated hammer bail arm 91 or I05 is pulleddownward to rockits corresponding hammer bail, at the same time loweringtie link I35 to a point Where it engages the lower edge of the slot inlink I34, thereby rocking contact pawl I21 clockwise. The rocking of thepawl disengages it from spring contact I29 permitting the contacts I29and I28 to open the circuit. The circuit remains open and cannot beagain closed until release of the digit key permitting return of contactball I 25 to normal by spring I 30, and the concurrent lowering of the'pawl I 21 to again engage its lip under spring contact I29 inpreparation for a succeeding punching operation.

The circuit completed by the closing of contacts I 28, I29, abovedescribed, passes through a two way transfer switch I36 mounted on therear of base I5 as can be seen in Figs. 4, 5, and 8. The transfer switchcomprises two contacts I31 and I38 having a common contact I40 mountedon a center spring I39. One or the other of contacts I37 and I38 isalways closed, and they are controlled by a contact slide I4I abuttingthe common center spring and extending through a slot in the base I5. Aroller I42 mounted on the slide engages the side surface of the carriageescapement rack 2I. As best seen in Fig. 10, the side of the carriageescapement rack is formed with a cam I43 extending over a portion of itssurface, which cam, in cooperating with roller [02, acts to shift thecontact slide rearward away from the carriage escapement rack, therebybreaking contact l3! and making the contact I38. Electromagnets I03 andI00 are wired to the alternate contacts of the transfer switch as shownin the wiring diagram Fig. 11. Thus, when the card carriage is moved toits extreme right hand position preparatory to the punching of a card,contact slide roller I42 engages the side surface of the carriageescapement rack, permitting the spring action .of the center contactspring of switch I36 to close contact l3! completing the circuit tomagnet I06, it being the actuating meansfor driving punches 89 which, asaforementioned, are used for punching only in the upper zone of a ninetycolumn card. This circuit to magnet IDS-is thus maintained during theforty-five columnar space positions of the card carriage to permitcomplete punching of the upper zone upon the completion of which, as thecarriage proceeds leftward-to the forty-sixth space position, cam I43engages roller I42 to shift contact slide Ml rearward. Said shifting ofthe slide opens the contact I31 and closes contact I38 opening thecircuit to magnet I06 and closing the circuit to magnet M3, maintainingsaid circuit for the remaining forty-five columnar space positions ofthe card carriage. The linear distance between rows of punches -88 and89, being the equivalent of forty-five carriage spaces, the spacing ofthe carriage upon the perforation of the last upper zone or forty-fifthcard column by punches 89 will carry the card to a position where thefirst lower zone or forty sixth card column can be perforated by punches8B. In

- this manner the entire ninety columns of the card may be punched inone continuous and uninterrupted series of punching operations, the

transfer from upper to lower zone being effected automatically throughthe unique arrangement of the punches, transfer switch, and associatedmechanism.

Suitable means for conducting a source of electrical energy to thecircuit herein disclosed may comprise any such means known and familiarto the art. In the preferred embodiment such means comprises a dry diskrectifier in a combination circuit permitting use of either an A. C. orD. C. potential in the manner disclosed and fully described in theaforesaid Patent 2,l5l,232,'issued to Roggenstein March 21, 1939.

While I have described what I consider to be a highly desirableembodiment of my invention, it is obvious that many changes in formcould be made without departing from the spirit of my invention, and I,therefore, do not limit myself to the exact form herein shown anddescribed, nor to anything less than the whole of my invention ashereinbefore set forth, and as hereinafter claimed.
